1. A terminal device configured to communicate with a base station device, comprising:
a receiver configured to:
receive configuration for an initial UpLink Band Width Part (UL BWP) and configuration for an additional UL BWP via a Radio Resource Control (RRC) message; and
receive, in a common search space, a first Downlink Control Information (DCI) format scheduling a Physical Uplink Shared CHannel (PUSCH); and
a transmitter configured to transmit the PUSCH in an active UL BWP,
wherein one of the initial UL BWP and the additional UL BWP being activated as the active UL BWP,
bitwidth of a first field included in the first DCI format is determined based on a size of the initial UL BWP,
the first field indicates a value,
the value is calculated based on the size of the initial UL BWP, a number of a starting resource block for allocated resource blocks, and a quantity of contiguously allocated resource blocks, and
resource block numbering for the allocated resource blocks is determined within the active UL BWP and starts from a lowest Resource Block (RB) of the active UL BWP.
